Caching
In general, caching improves response time and reduces system load. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many Web sites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server 6.0 dynamic cache, a built-in service for caching and serving dynamic content.
This chapter discusses the benefit of caching on a WebSphere Commerce site.
We discuss:
- Types of caching
- Dynamic Cache Service (DynaCache)
- Edge Side Includes (ESI)
- Caching enhancements in WebSphere Commerce 6.0.0.1 and later
- Cache replication strategy for a large scale, highly available WebSphere Commerce system
- Monitoring DynaCache and ESI
